Why we built Gessa in the browser on WebGPU

A browser workflow connects creation, collaboration and play. WebGPU provides GPU rendering capabilities, with a WebGL2 fallback in Gessa’s engine.
A browser workflow for making and playing
We built Gessa around the connection between an idea and the game people play. Open the browser editor, create with AI and engine tools, and collaborate in the same project. Publish a game and share its play page with friends.
Models, textures, audio, scenes and game rules are part of the same creation workflow. You can inspect a change in context and decide what to build next, without installing a desktop game editor.
GPU rendering supports the experience
WebGPU gives web applications an API for graphics rendering and computation on a GPU. Gessa’s rendering implementation supports WebGPU with a WebGL2 fallback. The available path depends on the browser and device.
Graphics are one part of the engine. Gessa brings them together with game logic, physics, multiplayer and asset creation. Test your game on the devices you want players to use, then refine its scenes, controls and effects around that experience.
